A game isn't just leveling. In XI leveling could of taken you a year, a month, or a week, depending on when you played the game. MOst people aren't willing to spend a year leveling to max. People think "omg he leveled 1-50 week thats so lame my class means nothing", not that person leveled 1-50 in a week, didn't get guildmarks, didn't do class quests, didn't do main storyline quests, and such. Look at someone on the lodestone, i looked at a page 1-50 in 9 days, no quests done NONE!, No guildmark abilities, nothing! They had pl'd and then partied, rushed to 50 they have no money, no shards, no special abilties. and their gimp. Especially for a mage, you get 1-50 in a week with a mage, good luck on having fastcast and defense while casting or transcendence or the w/e of nature conj one. They're gimp ass 50 who cares, they'll need to spend another two weeks to a month upgimpin themselves unless they spam leves all day, which then that person is just sick and we should leave them alone to go get help.
If i didn't sort of know this person irl, i would so post there lodestone history. They got three guildmark abilities for their mage that don't matter the stats to other stats ones, because they haven't done ANY class quests, they haven't done any main storyline quests either, its hilarious.
What I'm trying to say is, because we've played the game for longer we know how it works, what you should need for your class and such. There are a lot of new players just burning with new exp system and I laugh at their 50s, they have no gear, no guildmarks nothing. And if you think guildmark abilities aren't important for your cross classing and such, that's a different story, and you're probably gimp too. there's 4 at max you need get em.
